I currently have a SFH with about $60K in equity in it and I am under contract for my second investment SFH in which I put 20% down ($35k). I want to purchase more properties to keep this momentum going.... What options do I have? Cash out refinance, HELOC.....And would a cash out Refi add PMI to my "new" mortgage?

Secondly, How long should I wait or do I have options to leverage my newest property to buy more without spreading myself too thin?

Thanks in advance for the feedback and I wish you all a prosperous real estate experience!!
